[FREE] If you choose—or are forced—to draw power from the likes of Adam Dunn or Mark Reynolds, pay attention to some of these ADP-challenged and undervalued names for BA help. But are they really keepers, and over what timeline?

Power sources Kyle Blanks and Mark Trumbo are both facing potential short-term marginalization, thanks to big offseason acquisitions by their current teams. We look at their 2012 seasons and three-year timelines, as well as Ruben Tejada’s keeper potential.

We extend our look at players with injuries that affected their 2011 performances --- and who were also affected by off-season activity and news. How do their 2012 and three-year outlooks project as of today?

Responding to the offensive sinkhole created by the loss of Victor Martinez (DH, DET), the Tigers shocked observers by agreeing to a nine-year contract with Prince Fielder (1B, DET) this week. The bad news is that Fielder moves to a far less-friendly HR venue in Comerica Park, which deflates HR to LHBs by 11% as opposed to 16% inflation in MIL. Still, the overall hitter-friendliness of the AL and Fielder's numbers--he's averaged over 38 HR, 15% bb% and a 165 PX over the previous five seasons--make park effects almost immaterial.

Here are some more names with shifting outlooks due to off-season player movement -- as well as injuries that impacted their 2011 performances and/or could put them behind the eight-ball to begin 2012. Once again, we consider their immediate and three-year outlooks.

Last week in this space, we focused on some names whose prospects have improved with offseason activity – and who could bring a relatively fast return depending on your league context and timeframe. This week we’ll focus on some players for whom opportunity appears to be the primary 2012 attraction – but who still merit some attention.

We’ll spend January offering up our takes on the impact that the 2011-12 offseason has had on KL options, both immediate and longer-term. Sure, the landscape still has time for more change prior to Opening Day, and some speculation is involved – but KL owners who are active now should pay attention. The names listed below were all mentioned in our "dynasty reload" series -- and their immediate opportunities have improved markedly since then.
